Sittenfeld is the author of The Man of My Dreams, Prep, American Wife, and Eligible. You Think It, I'll Say It is her first short-story collection. It contains stories of jealousy, greed, and revenge, all centered around how others' lives appear to us in the age of social media.

You Think It, I'll Say It isn't the only book-to-screen adaptation Witherspoon has on her plate right now. Her collaboration with Zendaya, A White Lie — based on Karin Tanabe's novel, The Gilded Years — tells the story of a young, mixed-race woman who passes for white and enrolls at Vassar College in the late 19th century. Her as-yet-untitled comedy project, co-developed with Jennifer Aniston, is based on Brian Stelter's Top of the Morning, and has already been greenlit for two seasons, according to Variety. With Kerry Washington, Witherspoon will bring Celeste Ng's acclaimed novel, Little Fires Everywhere, to the screen. And that's not to forget her myriad other book-based projects, such as Wild, Gone Girl, A Wrinkle in Time, and, of course, Big Little Lies, which will return for its second season sometime next year.

Witherspoon has her own book coming out this year. Out Sep. 18 from Simon & Schuster, Whiskey in a Teacup will bring the Hollywood star's Draper James lifestyle site to store shelves. The title comes from her grandmother's adage that "the combination of beauty and strength made southern women 'whiskey in a teacup.'" Whiskey in a Teacup is available for preorder now from your favorite bookseller.
